With ATX 3.1 compliance, the ASUS Prime 850W Gold meets the latest power supply standards, offering tighter voltage regulation and improved current delivery for modern hardware. It also features comprehensive protection mechanisms including OPP, OVP, UVP, SCP, OCP, and OTP, ensuring your system remains safe even under heavy loads or during unexpected surges.
Whether you're assembling a next-gen gaming rig or a productivity powerhouse, the ASUS Prime 850W Gold PSU is built to deliver consistent performance. With an MTBF of over 120,000 hours and backed by a 10-year warranty, you can trust it to power your system reliably for years to come.
